CONVEYER.

SPECIFICATION forming part of Letters Patent No. 391,756, dated October 23, 1888.

Application filed May19,18f:8. ScrialNo. 274,350. (No model.)

To aZZ whom it may concern.-

Be it known that I, DANIEL M. MAXoN, a citizen of the United States, residing at Bay City, in the county of Bay and State ofMichigan, have invented certain new and useful Improvements in Gonveyers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apro pertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon,which form a part of this specification.

This invention relates to improvements in I 5 conveyer-s, or devices used for conveying sawdust, slabs, and other refuse in saw-mills, and in conveying grain or other material of alike nature from one portion of a mill or store-room to another.

Theinvention consists, first, in an improved form and construction of the bar or flight, second, in the improved device for detachably securing the bar or flight to the conveyerchain; and,third, in the combination,construction, and arrangement of the several parts of the device.

The objects of this invention are to so arrange a conveying device. that the bars or flights thereof may be easily and cheaply made 50 of a bar of wrought-iron, whereby the wear and strength of the flights are greatly increased without being rendered cumbersome or of too great weight.

A. second object is to so construct a convey- 3 5 ing device that the flights or bars thereof are secured to the conveying-chain in such a manner that they may be easily and quickly detached from the chain and moved to another position and again attached to the chain with- 0 out destroying or changing the attaching de vice.

A third object is to produce a conveyer having crossbars or flightsthat may be constructed entirely of metal in a manner that the liability of b'reakages is reduced, and that may be used for carrying refuse into a furnace without liability of taking fire.

These objects are attained by the devices illustrated in the accompanying drawings, in

which- Figure 1 is a plan view of my improved conveyer ready for use. Fig. 2 is a side view of the same, enlarged, with the trough removed. Fig. 3 is a side view of the bar-fastening device detached. Fig. 4. is a plan view of the same. Fig. 5 is a plan view of the conveyer bar or flight detached. Fig. 6 is a transverse section of Fig. 1.

In the drawings, a represents a chute'or trough having the bottom I) and sides a, and may be of any desired length or other dimension suitable for the work required.

dis an endless chain of the ordinary and common welded-link form, and is placed with one portion upon the bottom 1), between the sides 0, in the ordinary manner of con veyer-chains, and passing over supporting and driving sprocket-wheels at the ends ofthe conveyer-trough, the remaining or lower portion hanging beneath the-trough; or, if desired, the lower portion may rest in the trough, while the upper portion may hang suspended or supported upon slides above the trough.

e are the cross-bars or flights placed beneath and at right angles with the chain at suitable intervals, and these crossbars e are formed of a bar of wrought-iron of a suitable length and dimension, with its central portion, f, twisted at Z Z to a position to bring the width of the bar at the portion f at right angles with the end or wing pcrtions,g, thereof, which arranges the width of the wing portions 9, so that they will be at right angles to or perpendicular to the chain when the chain is resting upon the central portion, f, and between the twisted portions 1.

h is an elongated fasteninglink, having one end portion, 1, of a suitable dimension to allow the chain to pass freely through the link, while the opposite end portion, j,thereof is closed sufo ficiently to form a clutch and to grasp the vertical link of the chain between the adjacent horizontal links connected therewith, which clutch operates to retain the link h in position relative to the chain. Each end portion a and 5 j of the link is bent upwardly, leaving a lower level portion, k, which rests beneath and across the portionf and between the twisted portions Z of the crossbar or flight. The chain being slack, the fastening-link is placed over the chain,

with the upwardly-curved clutch endj catching upon the proper vertical link, and the portion of the chain between the ends i and j of the link is raised. The crossbar e is then passed between the portions 7c of the link, with the chain and the central portion,f, of the bar resting upon the portions 70 of the link,and with the portion at of the chain passing over the partf, and the chain on being drawn taut slides freely through the open endz'of the link, and securely retains the flight in position in relation to the length of the chain, while the twisted portions Z on each side of the link retain the flight against a lateral movement. To remove the flight or cross-bar, the chain is slackened and the part m lifted, and the crossbar is then free to be withdrawn; but so long as the chain is held reasonably taut by the carrying-sproekets the flights are retained firmly in position.

The advantages of this improved device are great, as the chain used is of the common form of welded-link variety and easily obtainable. The flights are constructed of ordinary rolled bar-iron, which is of the greatest durability, and the fastening-link is of a simple construction, and all of the parts can be easily made and repaired by any blacksmith without special machinery or appliances therefor; and a further advantage is that while the fasteninglink retains the flights in a proper position across the chain while performing the work required the chain, being capable of bending in all directions, allows the flights to turn to an angle with the line of movement and pass any obstruction which would otherwise cause abreakagc of the parts. Another and very great advantage is that by theimprovcd means of securing the flights to the carrying-chain they may be removed and replaced and the space between changed with great ease and without parting the chain or otherwise changing the parts of the device.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, 1s-

1. A conveyer-flight consisting of a bar of oblong form having its central portion twisted to a position at right angles with the end portions, substantially as set forth.

2. A device for securing a flight to a conveyer-chain, consisting of an elongated link having its ends curved upward, and having one end arranged to pass freely over the chain, and having the sides of its opposite end partially closed to form a clutch, substantially as and for the purpose set forth.

3. In a conveyer, the combination of the chain, and the flights provided with a horizontal portion beneath the chain, and vertical wing portions extending upon each side of the chain, and the elongated fastening-link having its sides beneath the flights and its ends upturned and reaching over the chain on each side of the said flights, and provided on one of the said upturned ends with a narrowed end adapted to grasp the vertical link between the adjacent horizontal links, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

DANIEL M. MAXON.
